Atomic mass the technical answer would be average atomic mass is the atomic mass found on the periodic table. Which statement correctly describes the average atomic mass of an element? The following questions require the use of a calculator. The final calculate step should serve as an answer key for the student, based upon the combination of isotopes, mass, and abundancies that they chose. Their numbers,the atomic mass which is measured by mass spectrometer is the real mass of the atom which also varies between atoms if they were to sum up all those isotopic masses and take the average the result will. Answer:the chlorine isotope with 18 neutrons has an abundance of 0.7577 and a mass number of 35 amu. The atomic mass is what these atoms actually weigh in atomic mass units. Calculate the average atomic mass. If you use the average atomic masses (instead of the mass of a specific isotope), the answer is the average mass of it's important to know average atomic mass because different isotopes of an element exist at different abundances. Explain why the mathematical reasoning was incorrect for any method(s) in model 3 that did not give the correct answer for average atomic mass (the one on the periodic table).
Relative formula mass worksheet | edexcel gcse science. Student exploration ph analysis answers these pictures of this page are about:atomic mass gizmos key. The average atomic mass is weighted average of atomic mass naturally occurring isotopes of element. The atomic mass is an experimental number determined from all of the naturally occuring isotopes of an element. In the average atomic mass gizmo, use a mass spectrometer to separate an element into its isotopes.
